Page 3: Operating And Safety Instructions
Operating and safety instructions This manual must be read carefully and all instructions must be followed ®MINI before starting up the EXKOP safety system. Any modification or careless installation of the components can result in failure of the entire system. This can result in explosion propagation which can cause the destruction of the equipment. -
Page 4: Description
The explosion pressure and flame must be vented to the outside. This is not always possible inside buildings, but can only be realized with considerable physical modification and large expenditure. ® ® The REMBE Q-Rohr offers a flameless explosion venting device with dust retention allowing safe explosion venting indoors. ®MINI... -
Page 5: Scope Of Exkop
®MINI The EXKOP System normally consists of the following components: ® ® Explosion venting by Q-Rohr or REMBE triple section bursting discs with KFD2-ST2-Ex1.LB electronic display electronic ®MINI EXKOP Safety Controller with dynamic self monitoring function and internal data memory as well as an alarm-control... -
Page 6: Function
Normal production sequence The QV II Quench Valve (D) is open to the full pipe diameter with no pressure drop across the valve. ® QV II Quench Valve, REMBE bursting discs ® and Q-Rohr (B) ensure secondary protection in the event of a dust explosion without interrupting any production sequence. -
Page 7: The Qv Ii Quench Valve
The QV II Quench Valve Note: It is important that all information contained in this manual will be followed exactly in order to ensure a proper function of the valve. Installation notes The QV II Quench Valve must be installed in the connecting pipes between the vessels to be isolated. -
Page 8: Maintenance Notes
A pressure gauge arranged at the tank serves for visual monitoring of the available operating pressure. ® The pressure regulator and pressure switch, which settings are set at REMBE , may only be altered after consulting with our service department. All warranty claims ®... -

4.2.1 Input modules The transformer isolated barrier KFD-ST2-Ex1.LB is used for signaling the status of ® ® the connected bursting discs or REMBE Q-Rohr . Upon activation of the Q-Rohr or ®MINI other safety devices, a signal is immediately sent to the EXKOP Safety Controller. -
Page 11: Internal Data Storage
4.2.3 Internal data storage A change of operating condition, faults and failures of the supply voltage are stored ®MINI internally in the EXKOP Safety Controller in chronological order. The storage capacity is sufficient for storing events over a period of one year. Storage takes place by means of ring storage, i.e. - Page 12 Schedule of different function ® MINI Input EXKOP terminal X1.16 X1.17 X1.18 Function 2 - 2 2x (1 - 1) 2 - 1 1 - 2 1 - 1 2 - 2 *) 2 - 2 *) 2 - 2 *) terminal +24VDC X4.16...

- Page 20 Installation Instructions for QV II Quench Valve Preparation of installation place Pressure The pipe work has to be fitted with counter flanges reducing valve (preset) according to the mounting and installation manometer instructions. Mounting of the QV II Quench Valves Be sure to allow the counter flanges to cool after welding.
- Page 21 Vacuum conditions for QV Quench Valve If you expect vacuum conditions in the process a bypass to the QV Quench valve must be installed. The bypass eliminate differential pressure between the process and interior of the Quench seal. This bypass assures full bore opening of the Quench Valve.
